Eco-hydrological Functions in Forested Catchments of Southern Chile
(Springer New York, 2020-03)Ecosystem functions in forests can vary significantly after disturbance, depending on changes in vegetation structure during succession and soil biophysical characteristics. We examined streamflow regulation, water storage ... -
Effects of long-lasting social isolation and re-socialization on cognitive performance and brain activity: a longitudinal study in Octodon degus
(Chile. Universidad Mayor, 2020)Social isolation is considered a stressful situation that results in increased physiological reactivity to novel stimuli, altered behaviour, and impaired brain function. Here, we investigated the effects of long-term social ... -
Environment and COVID-19: Pollutants, impacts, dissemination, management and recommendations for facing future epidemic threats
(Elsevier, 2020-12)Coronavirus disease 2019 (COVID-19) has become a global pandemic. Its relationship with environmental factors is an issue that has attracted the attention of scientists and governments. This article aims to deal with a ... -
Environmental signature and health risk assessment of polybrominated diphenyl ethers (PBDEs) emitted from a landfill fire in Santiago de Chile
(ELSEVIER SCI LTD, 2023-08-01)Polybrominated diphenyl ethers (PBDEs) have been used as flame retardants in building materials, electronics, furnishings, vehicles, airplanes, plastics, polyurethane foams, and textiles for many years. Currently, the ... -
Exclusion of Small Mammals and Lagomorphs Invasion Interact with Human-Trampling to Drive Changes in Topsoil Microbial Community Structure and Function in Semiarid Chile
(Facultad de Ciencias, 2018)Species losses and additions can disrupt the relationship between resident species and the structure and functioning of ecosystems. Persistent human-trampling, on the other hand, can have similar effects through the ... -
Exploring Perceived Well-Being from Urban Parks: Insights from a Megacity in Latin America
(Chile. Universidad Mayor, 2020)Urbanization has impacted biodiversity and ecosystems at a global scale. At the same time, it has been recognized as a driver of the physical and emotional gap between humans and nature. The lack of direct contact with ... -
Exploring the theoretical and practical implications of eigenbehavior at the intersection of second-order cybernetics and ecosystem management
(Emerald Group Publishing Ltd., 2023-09-11)In this conceptual paper the authors aim to discuss the implications of a second-order cybernetic approach and eigenbehavior in ecosystem management. The authors argue that traditional management practices rely on the ... -
Fungal Diversity Analysis of Grape Musts from Central Valley-Chile and Characterization of Potential New Starter Cultures
(Univ Mayor, GEMA Ctr Genom Ecol & Environm, Chile, 2020-06)Autochthonous microorganisms are an important source of the distinctive metabolites that influence the chemical profile of wine. However, little is known about the diversity of fungal communities associated with grape ... -
Geographical origin determines responses to salinity of Mediterranean caddisflies
(Public Library of Science, 2020-01-13)Many freshwater ecosystems worldwide, and particularly Mediterranean ones, show increasing levels of salinity. These changes in water conditions could affect abundance and distribution of inhabiting species as well as the ... -
Global ecological predictors of the soil priming effect
(NATURE PUBLISHING GROUP, 2019)Identifying the global drivers of soil priming is essential to understanding C cycling in terrestrial ecosystems. We conducted a survey of soils across 86 globally-distributed locations, spanning a wide range of climates, ... -
Global homogenization of the structure and function in the soil microbiome of urban greenspaces
(AMER ASSOC ADVANCEMENT SCIENCE, 2021-07)The structure and function of the soil microbiome of urban greenspaces remain largely undetermined. We conducted a global field survey in urban greenspaces and neighboring natural ecosystems across 56 cities from six ... -
Global phylogeography and ancient evolution of the widespread human gut virus crAssphage
(NATURE PUBLISHING GROUP, 2019)Microbiomes are vast communities of microorganisms and viruses that populate all natural ecosystems. Viruses have been considered to be the most variable component of microbiomes, as supported by virome surveys and examples ... -
High similarity in the microbiota of cold-water sponges of the Genus Mycale from two different geographical areas
(PEERJ INC, 2018)Sponges belonging to genus Mycale are common and widely distributed across the oceans and represent a significant component of benthic communities in term of their biomass, which in many species is largely composed by ... -
High-frequency monitoring of hydrological and biogeochemical fluxes in forested catchments of southern Chile
(WILEY, 2021-05)The variability of rainfall-dependent streamflow at catchment scale modulates many ecosystem processes in wet temperate forests. Runoff in small mountain catchments is characterized by a quick response to rainfall pulses ... -
Highly masculinized and younger males attain higher reproductive success in a social rodent
(OXFORD UNIV PRESS INC, 2018)Alternative morphotypes have been reported in males of different taxa. In some mammals, highly masculinized and slightly masculinized males represent 2 opposite ends along a gradient of phenotypic variation in males. This ... -
Insights into gene expression responses to infections in teleosts using microarray data: a systematic review
(Blackwell Publishing Asia, 2021-01)The rapid growth of production in aquaculture in the last decades has brought unwanted consequences affecting fish health and increasing the susceptibility to different infections. This systematic review aimed to analyse ... -
Invasion dynamics of the European bumblebee Bombus terrestris in the southern part of South America
(NATURE PORTFOLIO, 2021-07-27)Invasive species are one of the main biodiversity loss drivers. Some species can establish and thrive in novel habitats, impacting local communities, as is the case of managed pollinators. In this regard, an invasive ... -
Is the same pollinator species equally effective in different populations of the generalist herb Alstroemeria ligtu var. simsii?
(EDICIONES UNIV, CONCEPCION, 2019)En esta investigación estimamos la efectividad de polinización en tres poblaciones de Alstroemeria ligtu. Los resultados muestran que Lasia es el género de polinizador más frecuente, cuya efectividad varía entre poblaciones. ... -
Is there spatial variation in phenotypic selection on floral traits in a generalist plant-pollinator system?
(SPRINGER, 2019)The selective role of pollinators on the floral phenotype has been identified as the main force behind angiosperm diversification. However, in generalized plant-pollinator interactions this association may not be that ... -
